Sounds like a feature request for deborphan, reassigning and retitling
accordingly.

cryptsetup.NEWS reads

cryptsetup (2:2.0.3-1) unstable; urgency=medium

    With this version, cryptsetup has been split into cryptsetup-run
    (init script) and cryptsetup-initramfs (initramfs integration).
    'cryptsetup' is now a transitional dummy package depending on
    cryptsetup-run and cryptsetup-initramfs.

So if you remove the transition package you'll also need to `apt mark
manual` the dependencies.  I guess deborphan could do that
automatically?

For what it's worth in your case marking ‘cryptsetup-initramfs’ only as
manually installed should be enough, because the package depends on
‘cryptsetup-run’.  On a system where the initramfs integration is not
needed, one could instead remove ‘cryptsetup-initramfs’ and mark
‘cryptsetup-run’ as manually installed.

Cheers,

Guilhem.
